Abstract

An electronic device is provided. The electronic device includes a housing, a substrate disposed in an internal space of the housing, a battery disposed on a plane identical with a plane of the substrate, a support structure disposed to at least partially overlap the substrate when the substrate is viewed from a top, an antenna structure configured to include a dielectric substrate and at least one coil member disposed in the dielectric substrate as an antenna disposed to at least partially overlap the battery when the battery is viewed from the top, a tape member configured to include a first region at least partially overlapping the support structure, a second region at least partially overlapping the antenna structure, and a connection part connecting the first region and the second region when the support structure is viewed from the top. The dielectric substrate may include at least one extension part extended from the dielectric substrate and configured to at least partially overlap the connection part when the antenna structure is viewed from the top. The at least one extension part may include a plurality of dummy patterns formed at designated intervals and/or in a designated shape.

First claim
